The Sun Hydraulics DNDMLLE (Material Number: DNDMLLE) is a manually operated, 2-position, 4-way directional cartridge valve designed to control the flow direction in hydraulic circuits. This direct-acting, balanced spool valve utilizes Sun's TwistLock manual override mechanism for operation, making it suitable for intermittent and infrequent use. The mechanical life expectancy of the manual control assembly is approximately 7,000 cycles. It offers several control options: the momentary-twist option (T) allows temporary shifting by twisting the knob clockwise and releasing; the detent-lock option (L) enables shifting into a mechanically detented position with a counterclockwise twist, which remains until twisted clockwise again; and the dual-operation option (D), which combines both momentary and detent controls. Notably, the detented position is not intended for load-holding applications but for temporary shifts only. The valve is designed to be hand-operated without modification or use of mechanical devices. Cartridges with EPDM seals are compatible with phosphate ester fluids but should not be exposed to petroleum-based substances as they may damage the seals. The valve features Sun's floating style construction to reduce internal binding risks from excessive installation torque or machining variations. It fits into cavity T-31A and belongs to Series 1 with a capacity of 10 gpm (40 L/min). It can handle a maximum operating pressure of 5000 psi (350 bar) and has minimal leakage at standard conditions. The operating torque is 10 lbf-in (1.2 Nm), while installation torque ranges between 30-35 lbf-ft (41-47 Nm). For maintenance, Viton seal kits are available under part number 990431006.

This manually operated, 2-position, 4-way directional cartridge is a direct-acting, balanced spool valve used to control the direction of flow in a hydraulic circuit. Manual operation is achieved via Sun's Twist/Lock manual override mechanism and is designed for intermittent (infrequent) use only.
- This valve is designed for intermittent use such as a manual override. The manual control assembly has a mechanical life expectancy of approximately 7,000 cycles.
- The momentary/twist control option "T" allows the operator to momentarily shift the valve by twisting the knob clockwise and releasing. Once released, the valve returns to its normal position.
- The detent/lock control option "L" allows the operator to shift the valve into a mechanically detented position by twisting the knob counter-clockwise. This detented position will be maintained until the operator twists the knob clockwise and allows the valve to return to its normal position. Please note that the detented position is not intended for load holding applications but for temporary shifting only.
- The dual-operation control option "D" allows the operator to either shift the valve momentarily by twisting the knob clockwise or shift it into a mechanically detented postion by twisting counter-clockwise. Please note that the detented position is not intended for load holding applications but for temporary shifting only.
- The control on this valve is meant to be operated by a person's hand. The control should not be modified, for instance fastening a lever to the knob. Under no circumstances should the control be operated by other mechanical devices.
- Cartridges with EPDM seals are for use in systems with phosphate ester fluids. Exposure to petroleum based fluids, greases and lubricants will damage the seals.
- Incorporates the Sun floating style construction to minimize the possibility of internal parts binding due to excessive installation torque and/or cavity/cartridge machining variations.
